I have a couple of 400 blocks that might need a sleeve or two.

My experience hasn't been great putting a single sleeve in a Pontiac, other than the 4 corners. When doing cylinders, 3,5,4,6, I have had to do them in pairs. They all need to have a shelf machined near the bottom of the bore for it to sit on. I leave the sleeves .010+ tall and put a torque plate on without gasket to really seat the sleeve. Usually leave it on a couple days, then machine the deck and hone it with plate and gasket. Sleeved blocks never seem to stay as straight and round as all iron blocks.
